Injuries have given Broncos fullback Peyton Hillis a chance to shine, but he could be slowed by the Jets defense.

Some players who may disappoint you in Week 13:

Peyton Hillis at New York Jets: The Denver Broncos rookie running back has performed admirably of late, but he'll be facing one of the stingiest run defenses in the NFL this weekend. The Jets haven't allowed a running back to reach the century mark this season, and they've held all but three running backs under 50 rushing yards. The Tennessee Titans' Chris Johnson and LenDale White, one of the league's top running back duos, combined for 11 rushes, 45 rushing yards and a fumble vs. the Jets in Week 11, so make sure this Peyton isn't in your starting lineup in Week 12.

Shaun Hill at Buffalo Bills: The San Francisco 49ers third-year quarterback has been a top six fantasy QB over the last three weeks, averaging 244.3 passing yards and two TD passes a game. Unfortunately for Hill owners, his date with Buffalo doesn't look promising. The Bills are allowing one touchdown a game through the air, and that includes the four passing TDs they gave up to the Kansas City Chiefs in Week 11 (two of which came after the Bills took a 40-17 lead.) Throw in freezing temperatures and a chance of snow, and Hill will be longing for a return to San Francisco.

Dwayne Bowe at Oakland Raiders: Steve Smith, Roddy White, Derrick Mason, Jerricho Cotchery and Lee Evans have averaged 2.4 receptions and 26.2 receiving yards vs. the Raiders this season, and cornerback Nnamdi Asomugha is a big reason why. According to STATS Inc., 11 passes were thrown in the shutdown corner's direction through Oakland's first nine games this season. Now, do you really want to start the Kansas City Chiefs youngster against him?

Chris Cooley vs. New York Giants: The Washington Redskins Pro Bowl tight end has hauled in five or more receptions in eight of his 11 starts and has been held under 50 receiving yards four times in 2008. In nine career meetings with the Giants, however, Cooley has averaged 3.2 receptions and 27.2 receiving yards a game. In addition, the New York defense hasn't been too kind to the position, allowing 26 catches, 279 receiving yards and a single touchdown to opposing tight ends through Week 11.

If you're looking for a great flex play with big upside look no further than New York Giants running back Derrick Ward. Prior to starting against the Arizona Cardinals last Sunday, he averaged approximately 13 total touches a game and has been producing well with a solid 5.0 yards a rush.

The 10-1 Giants will likely try to protect oft-injured starter Brandon Jacobs and increase the workload for his more than capable reserve. The Giants offense, which averages more than 32 rushing attempts per game, should provide Ward with significantly more opportunities to raise his fantasy profile.

The Seattle Seahawks finally showed a semblance of a running game against a steady Washington Redskins defense in Week 12.

Maurice Morris spearheaded the attack with 103 yards on 14 carries and had three catches for 10 yards and a touchdown.

Scoring his second touchdown in two weeks, Morris has been more productive than presumptive No. 1 back Julius Jones. He was pegged to share carries with Jones earlier in the season but was halted by a sprained knee.

Now that he's healthy, the versatile Morris could receive a consistent workload. He's on the waiver wire in about 80% of leagues polled on major websites.

When the playoffs begin, it's one and done so you should give your roster a checkup and see just how ready it is for your run to the league title.

•Backup quarterbacks: Ideally you should have three QBs on your roster and not be caught in a jam because two of your guys are injured the same week. It happens — don't let it happen to you.

•Weather check: Players in domes or warm weather venues normally fare much better than those playing in wet, windy games. Don't rearrange your roster based on a mere chance, but it pays to have a warm weather player to use over your normal starter if the goal posts can't be seen because of a blizzard.

•Dump dead weight: We all have a player or two on our rosters that we never use. Maybe they are developmental guys that never panned out or an ex-starter who turned into a flop. But if you can't imagine using the player, then dump him for an additional kicker, defense, tight end or whatever. Carry options for your starting lineup, not dead weight you'll never use.

Despite totaling 47 yards and no touchdowns against the New England Patriots in Week 12, Miami Dolphins running back Ronnie Brown is a must start.

Brown rushed for 101 yards against the Oakland Raiders in Week 11. He scored a touchdown in each of the two games prior to that contest.

Besides, playing the St. Louis Rams will provide Brown with the spark he needs to rebound from a poor performance. St. Louis' defense has surrendered at least one rushing touchdown in every game. In fact, the Rams have permitted two or more rushing touchdowns in each of their previous three contests. In their last seven games, the Rams have allowed six running backs to gain at least 100 rushing yards. One of those players, the Arizona Cardinals' Tim Hightower, has failed to total more than 37 rushing yards against any other team.
